Microwave transmitter and receiver**53,000Microwave Transmitter and ReceiverThis ARCO range of equipment has been developed to demonstrate the properties of electromagnetic waves and as an aid to teaching the behaviour of visible light. The value of using microwave radiation for this purpose is two fold. Firstly, the concept that visible light is small section of a much wider band of frequencies may be introduced. Seconding microwave radiation share so many common properties with visible light that many experiments can be undertaken, which would otherwise be impossible due to limitations on time or equipment costs. Set includes one transmitter and one receiver

Linear air track/Air-track glider***27,500

8,000 Product Description:

This Edulab Mini Linear Air Track is designed to provide a cost-effective way of studying all aspects of dynamics in a virtually friction-free environment. The Linear Air Track is particularly effective in the observing and measuring of collisions where conservation of momentum is dramatically demonstrated. The Edulab Mini Linear Air Track kit contains everything required for an array of experiments covering: velocity; force and acceleration; potential energy; kinetic energy; conservation of energy; SHM; motion on level and inclined planes and more. The Air Track track itself measures 1.2 metres overall and is made from high strength 56 x 56 mm extruded aluminium. The tracks gliders are designed to accept standard slotted masses for additional loads and is supplied with a comprehensive accessory pack to enable every type of interaction.

An air source is required to operate the track, which can be provided by our Edulab Laboratory Air Blower (code: LINBLO) which is not included. It is supplied with a range of accessories including vehicles with mass attachments, catapults and buffers.

This requires an air blower to function:

Phillip Harries, A convenient alternative to the linear air track and blower.A sturdy and near frictionless stainless steel track that provides a compact environment for many investigations that might be done using a linear air track. Two heavy trolleys with hard, free-running wheels, are included, plus a set of 100g x 10g masses and a reel of cord. The track has solid end panels, with a rubber coating to buffer any collisions. A cm scale is screen-printed along the length of the track.Each trolley has a knob for attachment of cords for towing, and for ticker tape if that is the schools preferred method of capturing the motion of the trolleys. A 4mm socket on the trolleys top surface, allows for simple attachment of interrupter cards for use with light gates (Motion QED, see page 288) or timing software (see pages 345 to 368 for datalogging).A free-running pulley on one end of the track, allows a mass attached to a length of cord to be used as the accelerating force for one or two trolleys. Note that the trolleys can be stacked to immediately provide a trolley effectively of double the mass.Each trolley has a spring-loaded ram that can be set and released to provide reliable and repeatable launches. The ram can launch a trolley (single or double mass) from one end of the track, or simulate an explosion were two trolleys fly apart.The "Notes For Use" includes work on acceleration, exploring F=ma, investigations on an inclined plane, momentum and explosions.Track:1270 (inc pulley) x 120 x 60mm Mass: 3.1kgTrolley:155 x 76 x 55mm, Mass:0.65kg
